The Clean Air Act requires that all areas of the United States reach and maintain health-based standards for air quality. States are responsible for developing and executing plans for meeting these standards. Failure to meet federal air quality standards on time can result in severe economic sanctions for that area. When states take actions like changeouts to reduce emissions, they can claim credits that help them meet air quality standards.
The U.S. Environmental Protection Agency provides guidance and information to help you determine how to claim emissions credits. Click here to access the EPA guidance document.
